Golfballs.com Expert Description

Callaway Golf Big Bertha OS Graphite Irons provide players with the distance, speed, and forgiveness needed to shave some strokes off their final score. Advanced features including the all-new Exo-Cage, 360 Face Cup, and Standing Wave technology help golfers achieve the length, speed, and precision their game needs.

These irons also come standard with the UST Mamiya Recoil ES 460 graphite shaft, making them perfect for those with slightly slower swing speeds who would rather not deal with the vibrations from feedback.

Optimized Center of Gravity

In order to ensure that each club in the set performs it’s best, the Big Bertha OS Graphite irons utilize a tungsten-loaded Standing Wave technology in the sole that progressively lowers centers of gravity from the highest to the lowest-loft. Higher launch angles in the long-irons carries shots longer, while the short-irons give more shot control that’s perfect for approaching the green.

Enhanced Forgiveness and Speed

By incorporating the all-new lightweight yet durable Exo-Cage, weight can move to specific areas of the club head that will improve forgiveness, providing players with more distance even on mishits. This weight shift also enhances the performance of the 360 Face Cup technology by boosting COR to the USGA legal limit and quickening ball speeds off impact for even more length.

Features of the Callaway Golf Big Bertha OS Graphite Irons:

More forgiveness and ball speed from new exo-cage technology

Even more ball speed from next gen 360 face cup

Higher launch for longer carry from tungsten-loaded standing wave

Progressive center of gravity for increased control
